Application filed August 19, 1921.

T '0 all whom it may concern." I

Be it known that 1, CLIFFORD E. Monuroi a citizen of the United States, and a resident of Ravenna, county of Portage, and State of Ohio, have invented a new and useful Improvement inUnit Cabinet Constructions, of which the following is a specification,'the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle so as to distinguish itfrom other inventions.

The present invention relates to record cabinets for phonograph records and the like, and more particularly, to a unit case construction .whereby cabinets can be built up and added to easily and quickly. The present construction is similar to that shown in my oopen'ding' application for United States Letters Patent Serial No. 480,772, filed June 27, 1921, but-makes use of a simplified form of construction in which the individual units may be readily locked together but a form of construction which is simple and inexpensive to manufacture. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims. The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a side clevational view of a second unit; Fig. 2 is a sectional view through the upper frame members of two units looked together and a unit connected thereto; and Fig. 3 is a sectional view through units and a base showing the manner of attaching units.

The present units are formed in general like those described in my hereinbefore mentioned copending application, that is, each unit comprises an open frame having top and bottom frame members 1 and 2 and a back member 3. The front is merely two pieces of metal 4L which are secured to the top and bottom and which has a door 5, mounted on a pin 6. This door has limited movement which is controlled by a pin '7 which moves in an arcuate slot 8 cut in the door. The bottom of the unit is provided with a false Specificationof Letters 1?atei1t,

bottom 10 which is at a slight ia e A1 9"; 1 5, 1922 ,s riaino. 493,534. 3

incline, so .vtheifl -recond; will of the .-unit when the dooris opened.

The upper or top frame member isan open rectangular frame formed :ofa single piece of metal, one side 12 having a. back wardly turned-flange 13, at its vedge'while the other side- 15lisformed withan offset lower. edge ;;adapted to fituibetween. the flange j'13fl11d; the side 12- of the adjacent .unit.

The bottom provided with'flanges 13 and-offset ends 14, and of vcourse the flanges 13.1are turned away from each other so thatwhen a'iunit is slipped into place it is securelylocked against displacement.

frame members are similarly v The horizontal-surfaces or sides of the 7 top and bottoinmembersare provided with rebent folds .16 WhlCl1- -2 18 ofcourse. reversed as to direction so that each unit may be interlocked with the unit above and below as well as with the units on either side. The base member 18 will be provided with similar folds 17 to interlock with the folds 15 on the bottom, members. It will thus be seen that a cabinet of any size may be built up of these units which maybe readily added together, and of course the outside units will be closed by any suitable type of plates which may either be removable and interlock with the folds or offset ends or outside units may be furnished with sides integrally secured in place.

The offset ends and rebent flanges will be of such a size and so spaced that a snug, tight fit is obtained so that the frie tion will retain the units together securely against accidental displacement although they may be separated or added to by the user. The rebent flanges and offsets are so made that unitswhen assembled, will fit flush against each other to form a neat sub stantially dustproofcabinet and one which of units having complementary folds in their bottoms to interlock with the folds of the base, said units having their side members formed with edge portions adapted to interlock together to form a cabinet.

2. In unit cabinet construction, a unit comprising a frame having its top and bottom frame members formed of a single piece of metal having folds in its top and bottom, such folds being reversed to allow the unit to interlock with another, the sides of such units being provided at their edges with interlocking portions so as to allow the units to interlock with an adjacent unit.

3. In unit cabinet construction, aunit comprising a frame having its top and bottom frame members formed of a single piece of metal having folds in its top and bottom, one

side having its open edge bent back to form a locking fold, the other side having its edge offset to provide a lip adapted to interlock with the locking fold on an adjacent unit, such folds on the top and bottom frame members being reversed as to position so as to allow the unit to interlock with another similar unit at the top and bottom.

4:. In unit. cabinet construction, the combination of base members having a series of spaced folds in their tops, and a plurality of units comprising an open frame having its top and bottom formed of a single piece of metal having folds in its top and bottom, such folds being reversed as to position to allow the units to be interlocked with said base members and with similar units, the sides of the top and bottom frames being formed at their edges with a rebent flange and an offset lip to allow the frames to interlock with adjacent similar units.

5. In unit cabinet construction, the'combination of base members having a series of spaced folds in their tops, and a plurality of units comprising an open frame having its top and bottom formed of a single piece of metal having folds in its top and bottom, such folds being reversed as to position to allow the units to be interlocked with said base members and with similar units, one side of each top and bottom framehaving its edge rebent to form a locking fold, the other side of each top and bottom frame having its edge offset toform a lip adapted to look within such locking fold on adjacent similar units to form a cabinet.
